メタ倫理学と批判的合理主義

Abstract

This paper deals with some problems of meta-ethics in modern times. There are three views in meta-ethics: naturalism; intuitivism ; noncognitivism. It is taken for granted that each view is incompatible with the others, and in order to be consistent, we cannot but accept one of them. Against this common opinion, we claim that the three views have two prerequisites in common and that once we replace them with other ideas which are characteristics of Popper's critical rationalism, we can consistently propose the fourth view in meta-ethics.
